G-SHOCK MASTER OF G MUDMASTER Watch, 51mm - GG-B100XM-1AER

For fearless adventurers, a robust and durable Master of G MUDMASTER with a solid metal bezel.
Watches in the G-SHOCK Master of G line, developed for professionals operating in the most extreme environments, offer even more advanced features and superior durability. The MUDMASTER takes this concept further, with the ability to handle the toughest land environments, earning the appreciation and trust of rangers and rescue teams working in extreme conditions.
The GG-B100XM-1ADR features a silver-colored stainless steel bezel with a honing finish, which offers excellent scratch resistance, protects against mud and dust, and provides a matte texture that minimizes reflections. The bezel of the GG-B100XMB-1ADR, on the other hand, is made of stainless steel with a black IP coating and a mirror finish, for a combination of high scratch resistance and refined shine.
The GG-B100 MUDMASTER uses high-rigidity carbon for the case to contain damage and deformation and ensure extreme airtightness and high impact resistance. This timepiece is also equipped with a mud filter, a stainless steel case back, and a fine resin inner panel reinforced with glass fibers, which ensures a high level of protection against dust and mud. The main resin components of the case and strap are made of bio-based resin, obtained from renewable organic resources, designed to help reduce environmental impact.
Practical and functional, this watch is equipped with a digital compass, altimeter/barometer, thermometer, and pedometer. In addition to easy time adjustment with the dedicated G-SHOCK app, many other useful functions are available, including the mission log, which automatically records altitude data acquired by the watch and route data acquired by the smartphone.

FEATURES

Stainless steel exterior with refined craftsmanship that highlights the aesthetic of practical elegance
A characteristic element of the robustness-oriented design, the bezel conveys a strong presence. Made of stainless steel, its complex shape of multiple surfaces and contours was shaped through forging. The top surface, beveled edges, and sides are finished with different polishing techniques.
The GG-B100XM uses a silver bezel with a smooth matte finish that improves resistance to mud and dust and reduces light reflection, providing a calm and discreet texture. The GG-B100XMB features a black ion-plated bezel with a mirror polish, combining high scratch resistance with a refined metallic shine.

Shock, dust, and mud resistant structure thanks to carbon fiber-reinforced resin
The carbon fiber-reinforced resin case protects the module, offering solidity, lightness, and excellent resistance to the elements. The gaskets are applied around the buttons to ensure an airtight seal, guaranteeing reliable resistance to dust and mud even in difficult environments. Carbon fiber-reinforced resin is also used for the cover that encloses the case back and for the moving parts on the lower part of the strap, improving both durability and comfort of use.

Quad sensor supporting land missions
In addition to the triple sensor that measures compass detection, altitude/barometric pressure, and temperature, the watch is equipped with an accelerometer for step counting. By collecting various data, the Quad sensor simplifies the monitoring of environmental changes and activity history, helping to ensure reliable performance in land missions under the most difficult conditions.

bio-based resin
The main resin components used for the case, strap, and other parts are made with bio-based resin.
